Whiteside has apparently made amends and done the work needed to regain the staff's trust -- no easy task.

Last season, Whiteside played in 10 games, making 17 total tackles, tallying three sacks, four tackles for loss, two forced fumbles and one pass deflection. His reinstatement adds to an already-very deep outside linebacking corps that is expected to be one of the most dependable units on the team going into the 2012 season.
